IMPROVEMENTIN LAnNTERNs.

' Specilication forming part of Letters Patent No. 144,200, datedNovember 4, 1873,' application led October 9, 1873.

To all whom 'it may concern:

Beit known that I, EDGAR K. HAYNEs, of the city of Boston, in the countyof Suffolk and State of Massachusetts, have invented certain new anduseful Improvements in Lanterns an d" Lamps 5 and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use Y it, reference being had to the accompanyingdrawings which form tion.

My invention relates to vimprovements on lanterns for burninghydrocarbon oils 5 and consists in improvements on an invention forwhich Letters Patent of the United States were granted to me bearingdate March 18, 1873, No. 136,994, and the object of my invention is toren der such lanterns thoroughly portable and to prevent the flame ofthe lamp from being extinguished by currents of air under anycircmnstances or conditions of the weather, and to allow free passagefor anywater accumulating in the lantern away therefrom.

In the accompanying drawings, Figure l represents an external view, Fig.2 a section, and Figs. 3 and 4t details views, of a lantern arrangedaccording to my invention.

My invention consists, first, in the formation of holes in the plate ffor the free passage of water from the lantern and the addition ot' anannular plate, g, to counteract the eft'ect of the draft through theholes f and cause the greater portion of the air to pass to the centerand under the burner.

a is the lantern, constructed with an external frame, a', which supportsand retains the top b and bottom c correctly in position. d is theglobe, supported at its upper end in a ring, b', and at its lower end ina ring, c'. The lamp c in the arrangement shown in the drawings isretained in position in the lower part ofthe lantern by means ofbayonet-joints a, arranged on each side of the lantern, so that bysimply turning the lamp e the same may be removed part of thisspecifica- Vtor cleaning, lighting, or other purposes.

This means of holding the lamp e in position, however, forms no part ofmy present invention, and otllermea-ns of holding the lamp e in positionmay be employed. f is a curved dished plate, which is affixed to theburner c'Z and is provided with a series of smallholes, f', and, whenthe lamp e is in position in the lantern, forms the bottom of theinterior of the same. g is an annular'dished plate provided with a hole,g1, in the center, of sufficient size to allow of the passage of theburner there-` through. This annular plate is provided with a series ofholes, g2. h is an annular detlector for the purpose ot' conducting theexternal air down through the small openings c5 in the ring c', as shownby the arrow l in Fig.' 2. Such air then impinges on the plate j', andis thereby caused, with the aid of the annular plate g, to take the formof a wave having a curvilinear motion, such that it shall be directedunder the burner c?, and upward to the flame through the center, asrepresented by the arrows 2. In the event of a greater wave of airpassing in on one Vside ot' the lamp than can pass up through the conec2 such excess will be conducted under the burner, as shown by the arrow3, to the opposite side of the globe, and over the burner to the laine,when it will amalgamate with the upward current from the iiame, so thatno part of the wave shall impinge upon the exterior of the cone e orpass down through the burner. The series of small holes are formed inthe annular ring g at g2 to prevent stagnation or a tendency to Vavacuum near the globe, the current of air therefrom passing up, asindicated by the arrows 4.

Any water passing into the lantern through the detlector It will passaway through the holes f in the plate f',- eare must, however, be takenthat these holes are not sufficiently large or close together to form acurrent which would interfere with the current passing in through thedetlector.

The upper part b of the lantern I prefer to be constructed as describedin my former patent, herein referred to; but other arrangements of theupper part may be employed.

It will be readily understood by persons acquainted with the manufactureof lanterns that my improvements may be 4readily applied to lia-nd orother lamps for burning Vhydrocarbon oils in which ordinary chimneys areused in place of globes.

Having thus described my invention, what I claim, and desire to secureby Letters Iatent, is-

1. The annular dished plate g, provided with a central hole, g1, for thepassage of the burner therethrough, and holes g2, arranged, constructed,and operating substantially as shown and described.

2. The combination of a curved dislied plate7 j", and an annular plate,g, substantially as and for the purpose shown and specified.

have hereunto set my hand this 7th day of October, 1873.
